Musk faked the self-driving feature in the presentation, this feature is extremly risky in the Teslas, with erratic behavior, eg. causing accidents with random emergency breaks on the Highway and other issues, and yes, the quality of the cars are disastrous. The quality of Teslas including selfdriving capability is worse as those of any other e-cars from Japan or the EU. General valid for almost all US cars, because of this in the US the people prefer European and Japones brands, but only few people in the EU and Japon buy US cars. The difference is, that in the US the professional training of workers has nothing to do with those of European or Asiatics, which training is min.3-4 Years with final examen. In the US, in the factory, they show to the worker what they have to do in the production, without great technical explanations. As said, fast and cheap more important than quality.

Honestly with traditional car manufacturers now also offering very affordable options in direct competition to the model 3, I think there are several better value options, at least here in Europe.

The design philosophy of removing all physical buttons is also just plain stupid. Tbf, some other manufacturers also do this, but rarely as bad, and most are starting to backpedal.
